Expandable and collapsible cabinet

ABSTRACT

An expandable and collapsible cabinet contains a body being an elongated plate and including plural board portions and a plurality of bending portions; each bending portion integrally connecting with and between two abutting board portions, and between the each bending portion and each board portion is defined a grooved area to provide a collapsible space; a bottom cover; a top cover; when the body is folded into a rectangular frame by folding four grooved areas 90 degrees, the bottom cover and the top cover are covered on a bottom end and a top end of the body.

FIELD OF THE INVENTION

The present invention relates to a cabinet, and more particularly, to an expandable and collapsible cabinet.

BACKGROUND OF THE INVENTION

Conventional cabinet is assembled by glue or screws. However, after the cabinet is assembled by the glue, it can not be disassembled, so a size of the conventional cabinet is fixed without being stored in a small size.

Likewise, if the conventional cabinet is assembled by the screws, it can not be assembled and disassembled quickly.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide an expandable and collapsible cabinet which is stored and portable easily.

Another object of the present invention is to provide an expandable and collapsible cabinet which is assembled and disassembled quickly.

To obtain the above objectives, an expandable and collapsible cabinet contains:

a body being an elongated plate and including plural board portions and a plurality of bending portions;

each bending portion integrally connecting with and between two abutting board portions, and between the each bending portion and each board portion is defined a first grooved area to provide a collapsible space;

a bottom cover;

a top cover;

when the body is folded into a rectangular frame by folding four first grooved areas 90 degrees, the bottom cover and the top cover are covered on a bottom end and a top end of the body.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1-7, an expandable and collapsible cabinet 100 according to a preferred embodiment of the present invention comprises a body 10, a bottom cover 20, and a top cover 30.

As shown in FIGS. 1-3, the body 10 is integrally made of wood or cardboard and is an elongated plate on which a plurality of grooved areas are formed, wherein the plurality of grooved areas are equally spaced apart from and parallel to each other.

The body 10 includes plural board portions 11, a plurality of bending portions 12, and a covering portion 13. In this embodiment, there are six board portions 11 provided, and each board portion 11 has a predetermined thickness and width, six widths of the six board portions 11 are increased gradually from a left side to a right side of the body 10 as illustrated in FIG. 2. Each bending portion 12 integrally connects with and between two abutting board portions 11. In this embodiment, there are five bending portions 12 are provided, and each bending portion 12 has a predetermined thickness and width, five widths of the five bending portions 12 are increased gradually from the left side to the right side of the body 10 as illustrated in FIG. 2, and between the each bending portion 12 and the each board portion 11 is defined a first grooved area 121 to provide a collapsible space. The covering portion 13 is integrally connected on a free side of one outermost board portion 11, and between the covering portion 13 and the one outermost board portion 11 is defined a second grooved area 131.

As shown in FIGS. 1 and 4, the bottom cover 20 is integrally made of wood or cardboard.

The bottom cover 20 has a first C-shaped slot 21 formed on a top surface thereof and a first opening 22 defined on one side of the top surface thereof and communicating with the first C-shaped slot 21.

As shown in FIGS. 1 and 4, the top cover 30 is integrally made of wood or cardboard.

The top cover 30 has a second C-shaped slot 31 formed on a bottom surface thereof and a second opening 32 defined on one side of the bottom surface thereof and communicating with the second C-shaped slot 31.

In assembly, the body 10 is folded as illustrated in FIG. 4, and then four first grooved areas 121 are folded 90 degrees so that the body 10 is folded into a rectangular frame, thereafter a bottom end of the body 10 is inserted into the first C-shaped slot 21 of the bottom cover 20, and a top end of the body 10 is inserted into the second C-shaped slot 31 of the top cover 30 as shown in FIGS. 4 and 5, such that the bottom cover 20 and the top cover 30 are covered on the bottom end and the top end of the body 10, and two outermost board portions 11 of the body 10 allow being opened or closed between the first opening 22 and the second opening 32 as illustrated in FIG. 6, thus the expandable and collapsible cabinet 100 allows receiving objects.

Yet as desiring to collapse the expandable and collapsible cabinet 100, the bottom cover 20 and the top cover 30 are removed from the body 10, and then the body 10 is unfolded from the rectangular frame, thereafter each first grooved areas 121 of the body 10 is folded so that the body 10 is collapsed in a small size as shown in FIG. 1, hence the cabinet is assembled, stored, and portable easily.

In addition, the covering portion 12 is provided to be held by a user like a door grip.

Referring to FIG. 7, the bottom cover 20 and the top cover 30 are capable of being folded as well to decrease a stored size.

Likewise, there are four board portions 11 and three bending portions 12 provided in another preferred embodiment to obtain the body 10 as shown in FIGS. 1-10, thus expanding and collapsing the cabinet 100.

While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art.
